It was when I started running out of storage boxes that I realized I may have too many GaN chargers. I joke that if you casually throw a GaN charger in my home, you're bound to hit another one. Anyway, I have dozens of these things lying around, and having tested just about every major charger released in the last three years, I know what a good charger needs to offer.
So when I got started with the BMX GaNsta 140W (as puns go, the name gets an 8/10), it was clear that the charger ticked a lot of the right boxes. It has three USB-C ports, a USB-A port, foldable blade pins with EU, UK, and AU converters that make it easy to travel with, and 140W power over USB PD 3.1.
Oh, and it gets an LCD panel that shows real-time charging details out of each port, which is a must-have in a GaN charger in 2026. The GaNsta costs $89 as of writing, which is $10 pricier than Anker's charger, and $30 more than the last-gen 160W UGREEN Nexode Pro, both of which also have LCD screens.
The GaNsta is a little smaller than other 4-port chargers, but not enough that you'd notice the difference. Build quality is decent, and I didn't see any issues in the two months I used it. I tested the charger with my Find X9 Ultra, Pixel 11 Pro XL, iPhone 17 Pro, iPad Pro M4, and a dozen or so accessories — including 160W power banks — and it turned out to be reliable in day-to-day use.
I like that each port's power output is clearly labeled, and it takes a lot of the guesswork out of figuring out which port to use. The USB-C1 and C2 ports individually go up to 140W over the USB PD 3.1 protocol, and I tested this using a standalone power meter (Power-Z KM003C). I also like that the area around the ports has a slotted design to prevent scratches; this is a thoughtful design choice that makes a difference.
The LCD screen is the real star of the show. It shows real-time charging details, power going out of each port, and heat levels. The latter isn't quite as useful as you don't normally see thermal issues on a 140W charger, but it's there. And as AI needs to be shoehorned into every product these days, this thermal management feature is assisted by AI (however that works). Anyway, what you need to know is that even with all ports in use, the GaNsta doesn't have any issues with overheating.
You also get emoticons on the panel, and you can easily cycle through the various menus via the button at the bottom.
With four ports available, you get the ability to charge four devices at once. Of course, the total power budget is limited when all ports are in use, and with the GaNsta, you get 125W cumulatively: 65W + 45W + 7.5W + 7.5W. I would've liked to see 65W on both the C1 and C2 ports — like the latest Nexode Pro 160W charger — but that isn't the case.
That said, if you're just going to leave four devices to charge overnight, the GaNsta 140W does a decent enough job. The inclusion of a USB-C to USB-C cable along with travel plugs is a good move, and the size of the charger means you can easily throw it into a travel bag. What I'm not too sure about is the pricing; it is costlier than its rivals, and if you're willing to shell out $89, the new Nexode Pro 160W is a better deal at $99 as it has a retractable cable. If you don't need the built-in cable and like the travel-related accessories, the GaNsta 140W is a good choice.
